RAIL-CHAIR.

Specification of Letters Patent.

Patented Aug. 22, 1916.

Application filed June 16, 1915. Serial N 0. 34,434.

To all whom it may concern I Be it known that I, RAY THoivrPsoN, a citizen of the United States, residing at Sebring, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Rail-Chairs, of which the following is -a specification.

This invention relatesto rail chairs, and is adapted for use in theiprevention of lateral thrust to the rails at their joints An object of this invention is to provide an eflectual rail holder, which may be read ily applied to the rails, and expeditiously removed therefrom when desired.

Afurther object is to strengthen the rails at their joints and curtail the use of spikes as.

a direct securing means, to prevent thrust of the rolling stock passing over the rails, from bearing directly on the spikes.

Other objectsas acteristic features and scope of my invenreadily understood from the following description taken in connection with the accompanying drawings and pointed out in the claim forming apart of this specification. g

Referringto the drawings: Figure 1 is a perspective view of a rail chair constructed in accordance with my invention illustrating the application thereof, Fig. 2 is a cross sectional view of the same, Fig. 3 is a top plan view of the chair, a portionthereof being broken away to disclose details, and Fig. 4 is an elevational view of the detachable securing bolts used in the present invention.

In the drawings wherein is illustrated the preferred embodiment of this invention, a portion of a tie 1 is provided in order to illustrate the application of the invention.

Mounted upon the tie 1 is my improved rail chair, whlch comprises two sections 2 and 3, each of which is formed from a-single plate. The section 2 comprises a base portion 4 which is engaged beneath the base flange of rails 5 at the joint of the latter, as illustrated to advantage in Fig. 1. The section 2 has an enlarged portion 6 formed upon the upper face of the base'4, which in the present instance provides a splice 'bar for engagement with one side of the rails 5. The free marginal edge of the base 4 has its under face beveled, as indicated at 7, said margin being extended beyond the inner margins of the base flange of the rails 5, and

ha i g an enla gement 8 formed there n 69 well as the nature, char-- provide a channel 9 between the enlargement 8 and the inner margins of the base flanges of the rails 5 as shown to advantage in Fig. 1.

The section 3 comprises a splice-bar 10 for engagement with the opposite sides of the webs of the rails 5 from that with which the splice-bar 6 of the section 2 is engaged, the lower marginal edge of the section 3 being tapered and reversely folded beneath the beveled portion 7 of the base 4. A rib 11 depends from the inner face of the section 3, which is superposed on or over the free marginal edge of the tapered portion of said sec tion, and is adapted for-engagement in the channel 9.

It will be noted that the base 4 of the section 2 is tapered, as indicated by the dotted lines in Fig. 1, and shown to advantage in Fig. 3, the section 3 conforming to the configuration of the base 4, whereby said sections 2 and 3 are permitted relative movement in one direction, but will positively be held from displacement in the opposite direction, and engaged with the rails 5.

One end 12 ofthe section 3 is turned at right angles to the body, and is provided with an aperture therein which alines with a threaded recess in the enlarged portion 8 of the base 4. The recess in the portion 8 is adapted to receive the threaded shank 13 of a locking bolt or screw 14, the latter being preferably of a cylindrical configuration and having the threaded shank thereof of a uniform cross section throughout its entire length. A portion of the bolt, between one terminal of the threaded shank 13 and the head, is reduced as indicated at 15 to provide a ball-race, while the, portion 16 of the bolt between the reduced portion 15 and the head, is of a diameter substantially the size of the screw-threaded shank 13, and is smooth for sliding engagement with the aperture of the right angled end 12. By this construction, it will be appreciated that the sections 2 and 3 will be permitting their disengagement, but at the same time, holdingthe sections from displacement when desired.

Openings 17 are formed in the section 2,-

through the enlarged portion 8 of the base 4 and in the tapered margin of the section 3, said openings being alined when the sections 2 and 3 are ina'n engaged position, as shown in Fig. 3. The openings are adapted for the detachably engaged,

1 movement.

3 is then forced longitudinally along the side of the rails until it assumes the position shown in the drawings, when the rails will be securely clamped. It w1ll be understood that the locking bolt or screw 14 may be threaded into the section 2 as the section 3 is forced to the position shown in the draw ings. The bearing balls will serve as means to prevent the locking bolt or screw 14 from working out of the right-angled end 12, while the sections of the chair are in the position illustrated. It will therefore be appreciated that an effectual means is provided in order to hold the rails snugly in engagement at their proximate ends, at the same time, permitting the sections 2 and 3 to be readily disengaged, should it be desired to remove the rails from the tie 1. r

' It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention, and that various minor changes in details of construction, proportion and arrangement of parts may be made within the scope of the appended claim without sacrificing any of theadvan- V tages of my invention. V 7

Having thus fully described my invention,

what I claim as new and desire tosecure by 7 7 Letters Patent is:

A rail chair including a pair of sections, one of said sections having a flange formed on its upper face and adjacentone edge, the inner face of said flange being at an angle to the longitudinal axis of said section, a rail web engaging portion formed upon the opposite edge of said section, the body of said section forming a seat for rail ends, the

second section being provided with a tapered rib upon its lower face for engagement with said seat between the first-mentioned flange and the edge of the rail ends,'said first section having its first-mentioned longitudinal edge tapered and curved upwardly, and a flange formed upon the corresponding longia tudinal edge of the second-mentionedsection to surround said first-mentioned longitudinal edge of the first section,'said second section having a rail web engaging portion, and means for securing together said sections to prevent independent longitudinal movement of the same. a r

In testimony whereofl affix my signature in presence of two witnesses. or
